My tuner said to check the extension harnesses for the TBs and MAFs.

Ah, so you have the Stillen Supercharger setup.

Yes!
My TB extension harness still gives me limp mode at random/unpredicable times and has for years now. Might be fine for 6 months then plays up 2 or 3 times in a shorter (days/weeks) succession.
I still don't believe there is a proper fix for this including replacing the ext harness with a newer (upgraded) one from Stillen. Very annoying and unsafe!

Limp mode is where the car has almost zero throttle. That's not the symptom I'm having. I'm having a symptom where the car idles above 1k and won't rev past 2.5k.
